Abstract
Institute George-Lopez-1 (IGL-1) solution is a preservation solution with lower potassium and lower viscosity than the University of Wisconsin solution that has been recently used in liver transplantation. In the present series, we compare the outcome of liver grafts from brain-dead donors preserved in IGL-1cold storage solution, with cold ischemia times (CITs) longer than 8 hours and those less than 8 hours. Two hundred fifty-two liver transplantations performed from January 2014 to December 2016 at Hospital Santa Isabel, Blumenau, Brazil, were retrospectively analyzed. The patients were divided in two groups according to the CIT. Group I patients (N = 155) had less than 8 hours of CIT with a mean age of 54 ± 11.35 years, whereas group II patients (N = 97) had more than 8 hours of CIT with a mean age of 52 ± 12.5 years. There was no difference between the groups related to indication for liver transplantation and donor characteristics. The only difference statically significant on laboratory data was between the levels of aspartate aminotransferase at day 1 after transplantation. On day 7 post-transplantation there was no difference statistically significant between aspartate aminotransferase, alanine aminotransferase, and bilirubin levels between the two groups. Similar 1-year patient survival rates were found in both groups, with 85.88% for group I and 85.75% in group II. The IGL-1 solution has been shown to be safe, effective, and with good results in liver transplantations. Early graft function and 1-year patient survival rates did not differ when grafts preserved for less than 8 hours were compared to those with CIT greater than 8 hours.

Abstract
University of Wisconsin (UW) solution has been known as the standard solution for liver graft preservation. Alternative preservation solutions have been used in liver transplantation, such as histidine-tryptophan-ketoglutarate (HTK) and Celsior solution. Institut Georges Lopez-1 (IGL-1) is a new preservation solution with lower potassium and lower viscosity than UW solution that has recently been used in liver transplant. Data from 178 patients who received transplants from August 2008 to June 2013 at Hospital Santa Isabel, Blumenau, Brazil, were analyzed. All patients received grafts from brain death donors. In November 2011 we started to use IGL-1 as an alternate preservation solution. Therefore, 53 patients using IGL-1 preserved grafts were compared to 125 using HTK solution. The donor age in the HTK group ranged from 11-77 years, with a mean of 43.4 ± 4.8. In the IGL-1 group donor age ranged from 9-62 years, with a mean of 35.8 ± 4.5. Cold ischemia time in the HTK group ranged from 85-1145 minutes, mean 443.5 ± 183.5 minutes. In the IGL-1 group, cold ischemia time ranged from 85-670 minutes, mean 329.3 ± 134.8 minutes. The overall operative mortality rate was 14% (25 patients); in the HTK group, 14.4% (18 patients); and in the IGL-1 group, 13.4% (7 patients). One graft in the HTK group presented with primary non-function (PNF), 0.7%; there were none in the IGL-1 group. In our study, IGL-1 has been shown to be safe to use as a preservation solution for liver transplantation. Early post-transplant graft function was comparable to that observed with HTK solution, although a tendency for lower alanine aminotransferase levels was noticed. IGL-1 has been shown to be safe, cost efficient, and an effective preservation solution.

Abstract
BACKGROUND Counting the sponges is an important step in surgical procedures. A miscount may impact the patient's health, and it also has legal implications for the surgeon. This is an experimental study evaluating radio-frequency technology used in the perioperative period to identify surgical sponges left in the peritoneal cavity of swine. METHODS Radio-frequency labeled-disc identification tags were sewn into 40 surgical towels. Twenty labels had the ability to emit radio-frequency waves, and 20 labels were inert to radio-frequency identification. Twenty adult pigs that underwent laparotomy and randomly received two surgical sponges were scanned by a radio-frequency identification antenna. RESULTS This method presented a positive predictive value of 100% and 100% specificity and sensitivity, as all of the tagged surgical sponges were detected. CONCLUSION Radio-frequency identification has been proved to be a useful method for the identification of surgical sponges within the abdominal cavities of swine.

Abstract
CONTEXT The elevation of serum amylase and lipase are generally associated with pancreatic diseases. However they can be associated with different pathologies unrelated with amylase and lipase. CASE REPORT This paper aims to report a case of a patient diagnosed with nonspecific hyperamylasemia and warn of this possibility in the differentiation of hyperamylasemia. CONCLUSION The correct diagnosis of silent hyperamylasemia is important in order to determine whether there is the risk of pancreatic disease or if we are just ahead of a benign hyperenzymemia.
